Yeah its obvious the police don't enforce it i see 300zx, WRX, SS holdens all sort of high powered cars with P plates wacked on them, and the police don't seem to bother with them, however what are you goin to do if you are asked to weigh up your car etc?
What sort of penalties are there?
Do you think its fine to run around with a single turbo car, and can't you just turn of the turbos in some cases?
